Product details
Overview
TPS2836DR from Texas Instruments is a noninverting high-side/low-side dual MOSFET driver IC for synchronous-buck power stages, delivering 2.4-A typical peak output current, 50-ns max rise/fall times with 3.3-nF load, and adaptive dead-time control to prevent shoot-through-used in high-current single-phase DC/DC converters powering CPUs, FPGAs, and ASICs.
For engineers reviewing the TPS2836DR datasheet, TPS2836DR pinout, TPS2836DR application, or TPS2836DR equivalent, key selection criteria include TTL-compatible input logic, bootstrap vs. ground-referenced high-side configuration, −40°C to 125°C junction temperature range, SOIC-8 package compatibility, and dead-time control via DT terminal connection to the power FET node.
Technical Context
The TPS2836DR integrates independent high-side and low-side drivers with bipolar/MOSFET parallel output stages, enabling 2.4-A peak sink/source capability per channel under 12-V BOOT/VCC conditions. Its adaptive dead-time circuit monitors the BOOTLO node (FET junction) to enforce nonoverlapping gate drive timing.
It features an internal Schottky bootstrap diode, TTL-compatible IN and DT inputs with 1-V/2-V thresholds, and operates across 4.5–15-V VCC and up to 30-V BOOT-to-PGND-supporting both floating bootstrap and ground-referenced high-side configurations without external diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 4.5 V to 15 V - supports wide-input industrial and telecom DC/DC supplies |
| Peak output current | 2.4 A typical high-side source/sink - drives large-gate-charge N-channel MOSFETs in high-current buck stages |
| Rise/fall time | 50 ns max (high-side), 30 ns max (low-side) with 3.3-nF load - enables >1-MHz switching in compact power designs |
| Operating temperature | −40°C to 125°C virtual junction range - qualified for under-hood automotive and industrial ambient environments |
| Input compatibility | TTL-level IN and DT inputs - interfaces directly with PWM controllers like TL5001A without level-shifting |
| Dead-time control | Adaptive DT terminal tied to FET junction - eliminates shoot-through without fixed delay programming or external components |
| Package | SOIC-8 (D package), tape-and-reel (2500 pcs) - standard surface-mount footprint compatible with automated assembly |
Pinout & Package
TPS2836DR is housed in an 8-pin SOIC (D) package per JEDEC MS-012, with gull-wing leads, 1.27-mm pitch, and 5.00-mm × 6.20-mm body dimensions. Thermal dissipation rated at 600 mW at TA ≤ 25°C, derated 6.0 mW/°C above 25°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Digital input | Noninverting TTL-compatible control signal - directly accepts PWM from controller; logic high enables both drivers |
| PGND (Pin 2) | Power ground | Low-impedance return path for high-current gate drive loops - must be connected to FET source/power ground plane |
| DT (Pin 3) | Dead-time sense | Connects to high-side/low-side FET junction - enables adaptive nonoverlap timing to prevent shoot-through |
| VCC (Pin 4) | Supply input | 4.5–15-V bias rail - requires local 1-µF ceramic decoupling to PGND for stable gate drive |
| LOWDR (Pin 5) | Low-side output | Drives N-channel MOSFET source - sinks/source up to 3.5 A peak into 50-pF load at 12 V |
| BOOTLO (Pin 6) | Bootstrap return | Connects to FET junction - forms bootstrap capacitor return path and DT sensing node |
| HIGHDR (Pin 7) | High-side output | Drives N-channel MOSFET gate - delivers 2.4-A peak current with internal Schottky bootstrap diode |
| BOOT (Pin 8) | Bootstrap supply | Floats above BOOTLO - holds gate drive voltage for high-side FET using 0.1–1-µF ceramic capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive dead-time control | Eliminates shoot-through by dynamically delaying high-side turn-on until low-side FET is fully off, based on real-time BOOTLO voltage |
| Integrated Schottky bootstrap diode | Reduces external component count and improves charge-pump efficiency - no discrete diode required for bootstrap operation |
| TTL-compatible inputs | Accepts standard 0.8-V/2.0-V logic thresholds - interoperable with legacy PWM controllers without level translators |
| 2.4-A peak output drive | Supports fast switching of high-Qg MOSFETs (e.g., Si4410) in 3-A+ synchronous buck converters |
| −40°C to 125°C junction rating | Validated for continuous operation in thermally demanding environments including industrial motor drives and telecom rectifiers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-side/low-side MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2837DR | Inverting input logic (vs. TPS2836DR's noninverting); identical pinout, specs, and package | Requires inverted PWM signal or upstream inverter; otherwise drop-in replacement in same PCB layout | Select TPS2837DR when controller outputs active-low PWM or system-level logic inversion is preferred |
| LM5109BMAX | CMOS inputs (not TTL), higher 1.5-A continuous drive, no integrated bootstrap diode, wider 5–14-V VCC range | Suitable for lower-current designs; requires external bootstrap diode and level-shifting for TTL controllers | Choose LM5109BMAX only if CMOS interface compatibility and tighter VCC tolerance outweigh added BOM complexity |
Compared with TPS2836DR, TPS2837DR offers functional equivalence with inverted logic-ideal for systems where PWM polarity matches controller output-while LM5109BMAX trades integrated bootstrap functionality for CMOS input flexibility and tighter supply regulation, necessitating additional passive components.

FAQ
What is the function of the DT pin on the TPS2836DR?
The DT (dead-time) pin on the TPS2836DR connects directly to the junction of the high-side and low-side power MOSFETs. It enables adaptive dead-time control by sensing the voltage at that node, preventing simultaneous conduction (shoot-through) by enforcing nonoverlapping turn-on timing between HIGHDR and LOWDR outputs. This function is intrinsic to the TPS2836DR's internal circuitry and requires no external timing components.
Does the TPS2836DR require an external bootstrap diode?
No, the TPS2836DR includes an internal Schottky bootstrap diode connected between VCC and BOOT terminals. This eliminates the need for an external diode in bootstrap-configured high-side drive applications, reducing BOM count and PCB area. The internal diode is optimized for fast charge transfer and low forward voltage, supporting efficient bootstrap capacitor recharge during each switching cycle of the TPS2836DR.
What is the maximum allowable voltage between BOOT and PGND for the TPS2836DR?
The absolute maximum voltage between BOOT and PGND for the TPS2836DR is 30 V, as specified in the Absolute Maximum Ratings table. This rating defines the upper limit for the floating bootstrap supply voltage relative to power ground and must not be exceeded to avoid permanent device damage. Operation within the recommended 4.5–28 V range ensures reliable performance and longevity of the TPS2836DR.
Can the TPS2836DR drive both N-channel MOSFETs in a synchronous buck stage?
Yes, the TPS2836DR is explicitly designed to drive two N-channel MOSFETs-one high-side and one low-side-in a synchronous buck topology. Its high-side driver supports floating bootstrap operation, while the low-side driver uses a grounded source configuration. Both outputs deliver up to 2.4-A peak current, enabling efficient switching of low-rDS(on) FETs such as the Si4410 referenced in TPS2836DR application circuits.
What package type and reel quantity is supplied for the TPS2836DR?
The TPS2836DR is supplied in an 8-pin SOIC (D) package compliant with JEDEC MS-012, and shipped in tape-and-reel format with 2500 units per reel. The package features gull-wing leads, 1.27-mm pitch, and RoHS-compliant NiPdAu (NIPDAU) lead finish with MSL Level-1 rating (unlimited floor life at ≤30°C/60% RH). This packaging supports automated SMT assembly and long-term storage for the TPS2836DR.
